Louis Tomlinson 'In Trouble With New York Cops'

Boys will be boys, and Louis Tomlinson proved just that in New York this week - he was reportedly ticked off by cops for standing up out of the sunroof of a moving car.

The 'What Makes You Beautiful' hitmakers have been making waves in the Big Apple following their performance at the city's Madison Square Garden on Monday.

Harry Styles stepped out with rumoured girlfriend Taylor Swift, and Liam Payne received a dressing down from officials at the Empire State Building after taking aim at them on Twitter.com over a mystery incident.

And now it's emerged Louis has been a naughty boy, too - he found himself in trouble with the law after emerging from the sunroof of a car to film himself singing.
